Benefits of technology

This approach enhances bandwidth utilization efficiency by optimizing bandwidth distribution according to demand patterns, reducing underutilization and ensuring sufficient capacity where needed, while maintaining acceptable interference levels.

Problems solved by technology

In many cases, particularly in the case of space-based communications, these frequency reuse plans may be formed into the hardware of the device such that post deployment alterations are not feasible.
Despite the best planning techniques, many communications platforms experience underutilized capacity in some areas while other areas do not have sufficient bandwidth to service the desired capacity.

Embodiment Construction

[0022]The disclosed technology is directed to bandwidth allocations in wireless communication systems that provide frequency re-use. Wireless communication systems are disclosed that provide multiple spot beams to cover a geographic service region. The spot beams are associated with individual coverage regions within the overall geographic service region. The spot beams may be associated with one or more gateway terminals and / or one or more user terminals.

[0023]Frequency re-use is employed whereby unique combinations of frequency and polarization are associated with multiple spot beams. In one example, user terminal spot beams that are adjacent to one another utilize separate frequency / polarization combinations while at least some of the user terminal spot beams that are geographically isolated re-use the same frequency / polarization combinations. Likewise, gateway spot beams may re-use the same frequency / polarization combinations as other gateway spot beams from which it is geograph...

Abstract

A wireless communication platform utilizes flexible bandwidth assignment to re-allocate bandwidth between spot beams. The platform may assign a first combination of frequency and polarization (FP) to a first spot beam and a second combination of frequency and polarization to a second spot beam that is adjacent and at least partially overlapping the first spot beam. The platform may assign to the first spot beam a reserved combination of frequency and polarization during a first time period, and at second time, assign the reserved combination to the second spot beam. The platform may also assign the reserved combination simultaneously to adjacent spot beams by managing user of the reserved combination by geographically isolated terminals in the spot beams. The platform may further assign different portions of the reserved combination to adjacent spot beams without geographical limitations.

Description

CLAIM OF PRIORITY[0001]The present application is a divisional application of U.S. patent application Ser. No. 15 / 144,487, entitled “Flexible Bandwidth Assignment to Spot Beams,” by Hampton Chan, filed May 2, 2016 and published as US 2017 / 0215176 on Jul. 27, 2017, which claims priority from U.S. Provisional Patent Application No. 62 / 286,148, entitled “Flexible Bandwidth Assignment to Spot Beams,” by Hampton Chan, filed Jan. 22, 2016, both of which are incorporated by reference herein in their entirety.BACKGROUND OF THE INVENTION[0002]The present disclosure relates to technology for wireless communication systems.[0003]Wireless communication systems typically include a communication platform such as a dedicated terrestrial antenna, airborne platform, or communications spacecraft such as a satellite. Such platforms typically operate within regulations that allocate at least one operating frequency bandwidth for a particular communications service and specify, among other things, a max...
